    Long story short: Is it OK to allow the 'line-set' in my attic lay on top of the ceiling joists and insulation? I have a split unit in my attic in Fort Worth, TX. Thanks, Mike

    Not a problem as far as I know. But don't let the lines rest against the roof decking. When you get a new roof you risk a nail pucture.

    Long as it's not touching anything sharp, or near anything sharp, and long as it's out of the way (if you have a walk way up there) so it doesn't get damaged by crawling around, I'd say it's ok too.

    just make sure the suction line(the big one) is fully insulated with no copper showing or itwill drip water.

    Most important when running copper accross ceiling joists is make sure the suction line is fully insulated with no rips or cuts, also make sure that the copper is in a location so it wont get stepped on. I prefer to suspend line sets to avoid any possible problems, including noise and vibration, mice, heavy objects, and a possible trip hazard.
